However, stigmata of convulsive seizures may be absent. In some cases, a distinction between SUDC and SUDEP may be semantic as some SUDC cases had epilepsy syndromes retrospectively diagnosed based on genetic and other data, but epilepsy was not recognized before death. Pediatrics. doi: 10.23907/2017.020, 32. The registry provided ex vivo MRI imaging and brain examination by a board-certified neuropathologist. Whole brain analysis revealed hippocampal alterations of the DG as the most frequent microscopic alteration across all examined brain regions, although these were not specific to SUDC as three cases with these findings died from pathogenic genetic cardiac variants.

General autopsy findings such as tongue biting and urinary incontinence are occasionally seen in older children and adults; however, these only occur in a minority of cases and lack specificity (2, 3335). Hefti MM, Cryan JB, Haas EA, Chadwick AE, Crandall LA, Trachtenberg FL, et al. The Past, the Present and the Future. Imaging and volumetric assessments of SUDEP brains have demonstrated volume changes affecting brain regions responsible for modulating cardiorespiratory control, including atrophy in areas that protect against cardiorespiratory collapse, and increased volume in areas that predispose to apnea and/or hypotension (69, 70). The SUDC Foundation has recently sponsored a new annual award through the National Association of Medical Examiners (NAME) annual scientific conference. Sign up for our newsletter.

A history of minor blunt head injury identified in one quarter of SUDC cases from the initial SDSRP cohort, suggested a potential role for post-concussive mechanisms, although trauma has not been reported as a correlative risk for SUDC in subsequent analyses (1). doi: 10.1093/cercor/bht067, 52. (1995) 155:23469. There are no specific autopsy findings to confirm an acute seizure, and, if a death is unwitnessed, as occurs in more than 90% of cases, the diagnosis becomes speculative without strong supporting circumstantial evidence (32). These studies have been limited by sample size and lack of appropriate controls, which limit conclusions that can be drawn. The mums climbed the Welsh mountain in September to raise awareness and 8,000 for SUDC UK, a charity co-founded by Dr Nikki Speed, 43, of Hertfordshire. Tests were done for nine months but they couldnt find what had happened.. Hippocampal malformation associated with sudden death in early childhood: a neuropathologic study. A history of minor illness or fever in the 48 h prior to death, prior infection, minor head trauma, and peak winter incidence have also been associated with SUDC (1, 3, 18).

Multiple neurotransmitter defects of brainstem respiratory and autonomic pathways were identified in SUID brains, with abnormalities of the medullary 5-Hydroxytryptamine (serotonin) (5-HT) system implicated as a major network vulnerability for sudden death in infancy (6). Acta Neuropathol. You might wonder, if it is unexplained then how can there be a cause? But if there is a family history of any of these conditions, its best to get your child checked with a specialist at least once, for peace of mind., On the basis of the probable causes of sudden unexplained death of a child, NORD suggests that one must keep an eye out for signs of seizures.

Additional analyses have emphasized alterations of the granule cell layer (GCL) including granule cell dispersion (GCD) and focal dentate gyrus bilamination (FDGB) as key findings (Figure 1) (14, 40). Unlike prior reports, GCD or FDGB, were not prominent findings, raising questions about the importance of this finding as a morphologic marker of SUDC in this cohort. Sudden death in toddlers associated with developmental abnormalities of the hippocampus: a report of five cases. Autopsy data are an endpoint and have limited capacity to inform our understanding of the natural history of a disease process. Protocols for the investigation of unexpected infant death and recently published guidelines for SUDC are available; however, implementation remains problematic due to the persistent and systematic challenges described above (8, 2831). Kinney HC, Thach TB. She said: When I went to check on him, I knew something was wrong straight away as he was so still, Claire, 45, of Fleet, Hants, also has two daughters with husband Ronnie. (2016) 15:107588. As non-motor seizures may be associated with life-threatening apnea in early childhood the possibility that some SUDC cases represent SUDEP in children with undiagnosed epilepsy cannot be excluded (10). The good news is that doctors can treat this condition, and so they can also prevent death., Since SADS is caused by genetics, it is usually passed down from a parent to a child. Front Neurol.

Adelaide, SA: University of Adelaide Press (2018). The age of epilepsy onset influences SUDEP risk, which increases with earlier onset epilepsy, implying that developmental mechanisms might influence vulnerability (62, 64). 1. Alternatively, and perhaps more likely, is that prior studies suffered observer bias as there was greater tendency to consensus-based decision making without blinding. Ann Neurol. an overview. If and when risk factors are identified, such as prone sleep position for SIDS, then one might anticipate reduction in the risk of SUDC..

Thus, the SUDC Registry and Research Collaborative (SUDCRRC) at NYU Langone Health undertook a 5-year prospective analysis of 20 SUDC cases accrued through a registry where systematic sampling of whole brains was performed with blinded independent reviews conducted by neuropathologists (15). Sudden Unexplained Death in Childhood (SUDC) is relatively unknown though it is the 5th leading classification of death in toddlers. |Image courtesy: Pixabay, It could happen to a healthy child as well, and death comes almost immediately.

Retrospective, small SUDC studies with non-standardized methodologies most often demonstrate minor hippocampal abnormalities, as well as focal cortical dysplasia and dysgenesis of the brainstem and cerebellum. New York, NY: Springer-Verlag (2014). The most frequent DG alterations included alternating thickness, irregular configuration, focal GCL loss, and ectopic neuronal clusters. Understanding risk factors and the underlying biologic mechanisms of SUDC is essential for informing effective public health surveillance and developing strategies to mitigate risk in susceptible children. Shocked Sharon Anderson was at work in a hospital operating department when her 14-month-old, Tobias, was rushed in and died. As NORD explains, The disorders are usually caused by defects in specific proteins (enzymes) that help break down food into usable energy., Unfortunately, due to its sudden nature, preventing the sudden unexplained death of a child is almost impossible. 57.
